Senior CNC Machinist / Programmer — 5-Axis Production

Threat Tec•Hampton, VA

About The Position

Threat Tec, LLC, a rapidly growing Veteran-Owned Business, is the leader of Operational Environment (OE) replication and Threat Emulation/Wargaming solutions. Threat Tec brings innovative thinking and extensive experience to complex challenges for public and private sector customers. We work alongside our nation's defenders, developing solutions that drive success and protect our future. Join a team that is embodied by an unwavering commitment to professionalism, honesty, and innovation. READ THIS BEFORE APPLYING This is not a comfortable shop job where you run the same parts on repeat. We are a defense prototyping and low-rate production shop supporting U.S. national security missions. The work changes constantly. Materials change. Tolerances change. Timelines are aggressive. If your default answer to an unfamiliar job is "we can't do that," this is not the position for you. We need someone whose instinct is to figure out how to make it work. Position Summary Threat Tec is hiring a Senior CNC Machinist/Programmer to take ownership of our 5-axis machining capability and drive it from underutilized asset to revenue-generating production center. You will be the primary operator and programmer on a Haas UMC-1000SS 5-axis machining center and Milltronics ML18/60 CNC lathe, producing defense prototypes, low-rate initial production components, training aids, and precision-machined hardware for U.S. Department of Defense customers. You will work directly with our mechanical and electrical engineers to translate designs into finished parts. You will be expected to assess incoming manufacturing opportunities and find ways to execute them — not reasons to decline them. When a job requires capabilities beyond our shop, you identify what can be done in-house, what needs to be subcontracted, and you build the plan to deliver the complete package.

Requirements

Haas UMC-1000SS (or equivalent 5-axis VMC) Simultaneous 5-axis programming and operation. Not 3+2 positioning only. You must demonstrate proficiency in full simultaneous contouring on trunnion-style 5-axis platforms. Must be comfortable with 12,000+ RPM high-speed spindle operations. If you have only run 3-axis with a rotary table bolted on, do not apply.
Milltronics ML18/60 (or equivalent CNC/manual lathe) Proficient in both CNC and manual modes. Capable of programming and running turned parts from 0.25 " to 19" diameter. Thread chasing, boring, and gap-bed operations required.
CAM Software Must be proficient in at least one of: Mastercam, Fusion 360 (manufacturing workspace), or SolidCAM for 5-axis toolpath generation. Must be able to go from 3D model (STEP/IGES/SolidWorks) to verified G-code with minimal hand-holding from engineering.
Inspection / Metrology Experience with portable CMM arms (Faro, Romer, or equivalent — we run a Sylvac/Kreon arm). Must be able to perform first-article inspection, generate inspection reports, and hold tolerances to customer specification.
Minimum 7 years of CNC machining experience, with at least 3 years on 5-axis platforms
Proven experience machining aluminum 6061/7075, 4140/4340 steel, 304/316 stainless, titanium Ti-6Al-4V, and Delrin/UHMW plastics
Ability to hold tolerances of ± 0.001 " routinely and ± 0.0005 " when required
Proficient reading and interpreting GD&T per ASME Y14.5
U.S. Citizen (required for facility clearance and DoD work)
Must pass background investigation for Secret clearance
Must work on-site. This is a shop floor position. There is no remote option.

Nice To Haves

Large-format FDM/FFF 3D printing (we run a Modix BIG-120X V4 with 500°C capability for CF-Nylon and high-temp filaments)
CNC hot wire foam cutting (EPS/XPS — 3000 Shaper system)
Cerakote application and curing process
Basic welding (MIG/TIG) for fixture fabrication
Manual machining on Bridgeport-style mills and engine lathes
Active Secret or Top Secret clearance
Experience in a DoD prototype or LRIP (Low-Rate Initial Production) environment
Experience with Haas NGC control specifically
Naval systems, weapons systems, or UAS/drone hardware fabrication experience
Military veteran (any branch)

Responsibilities

Receive engineering drawings and 3D models from our ME team.
Program toolpaths in CAM.
Set up the Haas UMC-1000SS.
Cut parts.
Inspect them.
Ship them.
Evaluate incoming manufacturing opportunities alongside engineering. Your job is to tell us what it takes to make the part — not whether we should try.
When a job exceeds our in-house capability, identify the specific operation that needs to go out, recommend a sub-vendor, and manage that relationship.
Maintain the Haas and Milltronics — tool changes, offsets, preventive maintenance, coolant management. These are your machines.
Support rapid prototyping using 3D printing (Modix 120X) and foam cutting when jobs require mixed-method fabrication.
Perform first-article inspections using the Sylvac CMM arm and produce inspection documentation to government spec.
Work directly with our electrical engineer on integrated electro-mechanical assemblies requiring machined housings, brackets, or enclosures.
